In addition to Colombia, where it generates over 60% of the country’s production, it is active in exploration and production in the United States (Permian basin and Gulf of Mexico), Brazil and Mexico. Ecopetrol operates the largest refinery in Colombia, most of the country’s oil-pipeline and polyduct network and is significantly increasing its share of bio-fuels.

Achieving these estimates in the future depends on its performance under given market conditions, regulations, competition, the performance of the Colombian economy and industry, and other factors; therefore, they are subject to change without prior notice.
